oci: WithDefaultUnixDevices(): remove tun/tap from the default devices

thaJeztah · thaJeztah · commit a3ac1560076f · 2022-05-11T00:31:59.000+02:00
A container should not have access to tun/tap device, unless it is explicitly specified in configuration. This device was already removed from docker's default, and runc's default; - opencontainers/runc@2ce40b6 - https://github.com/moby/moby//commit/9c4570a958df42d1ad19364b1a8da55b891d850a Per the commit message in runc, this should also fix these messages; > Apr 26 03:46:56 foo.bar systemd[1]: Couldn't stat device /dev/char/10:200: No such file or directory coming from systemd on every container start, when the systemd cgroup driver is used, and the system runs an old (< v240) version of systemd (the message was presumably eliminated by [1]).
